Proposed changes to the state’s Medicaid program that would have parents pay a monthly $10 premium per person for coverage threatens to undo all the strides Florida has made in getting health care to the state’s poorest children, researchers warned Wednesday.

The premium, combined with several other changes lawmakers have asked for, could lead to 800,000 parents and children leaving the program because they couldn’t afford it, concluded a team from the Health Policy Institute at Georgetown University.

About 82 percent of those left without medical coverage would be children, 98 percent of whom live below federal poverty levels, the report concluded.

The Center for Children & Families (CCF), part of the Health Policy Institute at the McCourt School of Public Policy at Georgetown University, is an independent, nonpartisan policy and research center with a mission to expand and improve high-quality, affordable health coverage. Founded in 2005, CCF is devoted to improving the health of America’s children and families, particularly those with low and moderate incomes. Contact Us
